  The effects of planting date and gibberellic acid (GA3) on the growth and yield of a local cultivar of garlic were investigated during the growing period from November 2001 to April, 2002. The experiment was consisted of four planting dates (November 07, 22 and December 07, 22, 2001) and different concentrations of GA3 (0, 100 and 200 ppm). The objective of the work was to find out the appropriate planting time and effective concentration of GA3 on the growth and yield of garlic. Early planting favourably influenced plant height, number of leaves per plant, dry weights of leaves, bulbs and roots, total dry matter (TDM), leaf area index (LAI), crop growth rate (CGR), bulb diameter, individual bulb weight as well as yield. With the delay in planting time starting from November 07, the yield was chronologically reduced in later plantings. The highest bulb yield (2.67 t ha-1) was recorded from November 07 planting and the minimum (0.92 t ha-1) from December 22. There were deleterious effect of GA3 concentrations used in this experiment. Control plants produced higher yield than the plants treated with different concentrations of GA3. The interaction effect of planting dates and GA3 concentrations indicated that early plantings grown without GA3 showed better performance than the late plantings grown with or without GA3.

  The study was carried out in the Field Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh during the period from October 2000 to February 2001 to evaluate the influence of seed treatment with Indole Acetic Acid (IAA) by the concentration of 50 ppm, 100 ppm and 200 ppm on the growth, yield and yield contributing characters of two modern mungbean (Vigna radiata L.) varieties viz. Barimoog-4 and Barimoog-5. The two-factor experiment was laid out by Randomized Complete Block Design (RCBD) with 3 replications. In the experimental, seed treatment with 100 ppm IAA resulted the highest plant height, leaf area, leaf area index and number of seeds pod-1 (7.73). On the other hand, seed treatment with 200 ppm IAA resulted the highest Relative Growth Rate (RGR), Crop Growth Rate (CGR), Net Assimilation Rate (NAR), total dry matter, number of pods plant-1 (16.30), pod length (5.59 cm), fresh weight of pod plant-1 (13.00 g), dry weight of pod plant-1 (9.65 g), 1000-seed weight (40.10 g), seed yield plant-1 (4.99 g), harvest index (38.48). In addition, among the mungbean varieties, Binamoog-5 performed better than that of Binamoog-4.

  The experiment was carried to investigate the effect of plant growth regulators on the growth of soybean. Soybean (cv. BS-3) plants were sprayed with 0, 100 or 200 ppm of GA3 and IAA at three different times (20 and/or 42 days after sowing). The results indicate that physiological characters e.g. leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) were influenced by the application of the growth regulators. GA3 and IAA at 100 ppm significantly increased LAI, CGR, RGR and NAR. IAA at 200 ppm increased NAR. Double spraying at 20 and 42 DAS performed better than single spraying at 20 DAS and spraying at 42 DAS. Double spraying with GA3 and IAA had the highest CGR, NAR, LAI. On the other hand, single spraying with GA3 produced highest RGR and 200 ppm of IAA produced highest NAR. Spraying at 42 DAS of GA3 and IAA produced highest leaf area index and CGR over the single and double spraying. LAI, RGR, CGR and NAR progressed in similar patterns, regardless of the treatments. The treated plants attained high LAI, RGR, CGR and NAR than the control. This study clearly shows that 100 ppm of GA3 and IAA treated plants performed better than control and other treated plants.

  Effect of plant growth regulators on yield of soybean was investigated. Plants of soybean cv BS-3 were sprayed at three different times with two concentrations (100 and 200 ppm) of gibberellic acid (GA3) and indole acetic acid (IAA). GA3 at 100 ppm had regulatory effect to enhance the plant height, number of branches, number of leaves, leaf area per plant, number of flowers, number of pods, percentage of fruit set, number of seed per plant, seed yield per plant, 100-seeds weight and seed yield (t ha-1). On the other hand, 100 ppm IAA produced the highest plant height, number of flowers, number of pods, percentage of fruit set, number of seed per plant, seed yield per plant and seed yield (t ha-1), as compared to other plant growth regulators and control. IAA at 200 ppm increased number of branches, number of leaves, leaf area per plant, 100-seeds weight and net assimilation rate.

  Two varieties of mungbean (Vigna radiata L.) were compared for effects of seed treatment and foliar application of GA3 at 0, 50, 100 and 200 ppm on the growth contributing characters. Seed treatment with GA3 at 50 ppm increased the leaf area index, total dry matter, crop growth rate, while 200 ppm increased relative growth rate and net assimilation rate. Foliar application of GA3 at 200 ppm had higher relative growth rate, while that at 100 ppm had greater leaf area index, total dry matter, crop growth rate and net assimilation rate. Between the mungbean varieties, V1 (BARI-4) performed better than V2 (BARI-5) while the seeds were treated and an opposite result was found with foliar application of GA3. Significant varietal differences were observed in terms of physiological characters. The study indicates a high potentiality to increase the yield of mungbean in Bangladesh by the application of GA3.
